Disconnect the battery - both positive and negative terminals and remove battery from holder (better access that way). From underneath - remove the plastic shield underneath the front of the car. It is held on by a few bolts. Remove the upper radiator hose (some coolant will drain out). Also free the cable from the support bracket on the top of the platic fan housing. There is an overflow hose that is also clipped to the fan housing unlcip the hose and move it out of the way. From underneath, push in on the clips and the lower half of the fan housing will come out of the bottom. From the top - remove the two bolts holding the upper part of the fan housing and you should be able to work it out from the top. You should now have better visibility and access to the alternator. Loosen the belt tensioner (from below) and remove the belt. There are two mounting bolts on the alternator, a long one through the alternator and a second on the "dog ear" of the alternator. Once the alternator is free - you can get at the battery cable post and the other wires. The wiring harness can be removed by pressing in on the locking clip. Most difficult is the wiring harness support bracket. A short 10mm wrench can get to it. The alternator is now free but will have to be manipulated forward so that it sits below the fan. Once there - you can reach down from the top, and pull the alternator into the larger gap between the fan blades. While rotating the fan, bring the alternator around with it to the top and it will come out. To reinstall -- do everything in reverse. I recommend replacing the belt so you don;t have to do this again.

Trere are three bolts, tensioner bolt on bottom two bolts on top, the two on top are tough, three wires ground, power, and harness, locate all bolts and wires loosen to take off. For clearance raise vehicle on jack stands. Disconnect neg batt cable, remove all wires from alternator, remove drive belt, remove adjusting and mounting bolts, then remove alternator from below. It comes off easier than it goes back on. Install is reverse order of removal. Be sure to label wires for easier replacement.
Good Luck

You will have to loosen the belt tensioner located on the alternator. Also there are two or three bolts hoding the alternator on that you will have to take out. Make sure you disconnect the battery, then remove the wires from the alternator and remove it.
Please remember to rate this solution.
